Math expressions that equal 13

qaws [65]

Step-by-step explanation:

There can be a lot of math expressions that may equal 13. Here are some of the expressions that equal 13.

9 + 4 = 13

15 - 2 = 13

1 × 13 = 13

Now, let us consider some interesting expression

$x^3-x^2+x+7$

If the value of x = 2, then the expression will be equal to 13.

i.e.

$2^3-2^2+2+7=13$ ∵ when x = 2

Considering a word problem

'Tom has 10 oranges while Tony has 3 more oranges than Tom. How many oranges Tony has?

Let 'x' be the number of oranges Tom has.

The number of oranges Tony has = x + 3

as Tom has 10 oranges, so x = 10

Therefore, the number of oranges Tony has = x + 3

= 10 + 3 = 13

Therefore, the number of oranges Tony has = 13

"During their first swim through a water maze, 15 laboratory rats made the following number of errors (went the wrong way): 2, 1

velikii [3]

Answer:

mean = 7.8, median =5, and mode(s) =5

the shape of the distribution is positive skewed

Step-by-step explanation:

Find the mean, median and mode(s) for

2, 17, 5, 3, 28, 7, 5, 8, 5, 6, 2, 12, 10, 4, 3

the mean = sum of (2, 17, 5, 3, 28, 7, 5, 8, 5, 6, 2, 12, 10, 4, 3)/15 =

= 7.8

the median = 2, 2, 3, 3, 4, 5, 5, 5, 6, 7, 8, 10, 12, 17, 28, = the middle value, the 8th value falls in the middle = 5

the mode is the most occurring value = 5

2. Without constructing a frequency distribution or graph, would you characterize the shape of this distribution as balanced, positively skewed, or negatively skewed?

positive skewed or Right skewed because the value of the mean is greater than the median

A right skewed histogram is a positive skewed histogram (which means the tail is longer the positive direction) that have its tail to the right.For a right skewed histogram the mean has a larger value that the median because the peak of the skewness fall in the median range then the mean follow to the right. and the data drive the mean value to the right which increase in value.

How much force is needed to accelerate a 2,500 kg car at a rate of 4 m/s

docker41 [41]

Force is equal to mass times acceleration.

So to find how much force is needed do 2,500 x 4, which equals 10,000.

Force is measure in Neutons so the answer will be:

10,000N of force is needed to accelerate a 2,500 car 4 m/s.

Given f(x) = 2x³ 3x and g(x) = -3x2 +1, what is the value of h(3) where h(x) = (f+g)(x)?

Anni [7]

Answer:

19

Step-by-step explanation:

Operations of functions:

h(x) = f(z) + g(z)

h(x) = (2z³ - 3z) + (-3z² + 1)

Simplify or expand:

(2z³ - 3z) + (-3z² + 1)

Determine the sign

2z³ - 3z - 3z² + 1

Rewrite the expression

2z³ - 3z² - 3z + 1

Calculate:

Substitute z = 3 into

2z³ - 3z² - 3z + 1

Substitute

2 × 3³ - 3 × 3² - 3 × 3 + 1

Calculate
